Abstract
The synthesis of new poly[(vinyl 4′-alkoxyazobenzene-4-carboxylate)-co-(vinyl alcohol)]s 4a–c by Einhorn esterification of poly(vinyl alcohol) with 4′-alkoxyazobenzene-4-carbonyl chlorides 3a–c prepared in two steps from 4′-hydroxyazobenzene-4-carboxylic acid (1) is described. The degree of esterification is found to be about 85 mol-%. Infrared, 1H and 13C nuclear magnetic resonance and ultraviolet spectroscopical data of the obtained polymers are determined.
